You find this curious fact, that the more intense has been the religion of any period and more profound has been the dogmatic belief, the greater has been the cruelty and the worse has been the state of affairs. In the so called age of faith, when men really did believe the Christian religion in all its completeness, there was the Inquisition, with its tortures; there were millions of unfortunate women burnt as witches; and there was every kind of cruelty practised upon all sorts of people in the name of religion.

Science does not aim at establishing immutable truths and eternal dogmas; its aim is to approach the truth by successive approximations, without claiming that at any stage final and complete accuracy has been achieved.
